Escaping Braces

[SergioBenitez]

Can braces be escaped? I know that I can use raw, but that doesn't suffice when I want to mix variables with escaped braces such as below where name is in the context:

{% raw %}
    {{ hello }} {{ name }}
{% endraw %}

I'm looking for something like:

\{\{ hello \}\} {{ name }}

[Keats]

No way to do that no, is it not possible to do {% raw %}{{ hello }}{% endraw %} {{ name }} in your case?

[SergioBenitez]

No, the actual use case is more complex. It looks like:

<pre>
  {{
      ${{ bar }}
      something {{ foo }} blah {{ variable }}
  }}
</pre>

where only variable is actually in the context.

I think a nice way to work around this is to allow the brace type to be changed in a small block. So something like:

{% raw '[' %}
    {{ hello }} [[ name ]]
{% endraw %}

Where [[ name ]] is rendered by Tera.

P.S: Handlebars uses \{{ var }} (a single backslash) to escape braces.

The other way to do in Jinja2 is to do {{ "{{ var }}" }} which wasn't working until 0.7.2 which I just released.

There has been some people wanting another way to escape than raw and the string printing above in Jinja2 but it never felt that needed (cookiecutter/cookiecutter#11)

[Keats]

Can this be closed?

[SergioBenitez]

Sure, if {{ "{{ var }}" }} works as expected!

[Keats]

Should be ok but do re-open if you have an issue with it!

Hi @Keats I'm using Tera 0.7.2 because is the one that comes with Rocket 0.2.3, and this is not working for me.

Autoescaping is enabled in tera globally (didn't touched that because I can't in the present moment) and my template is this:

{% extends "blog/blog_base" %}

{% block content %}

    <h1>{{ titulo }}</h1> 

    {{ "{{ contenido }}" }}

    <br /><br />
    <a href="/blog">Blog</a>
    <br />

{% endblock content %}

{% block gototop %}
    {{ super() }}
{% endblock gototop %}

But it simply displays {{ contenido }} in the HTML output, when I want the variable value without processing.

[Keats]

You want {{ contenido | safe }} if contenido contains HTML. {{ "{{ contenido }}" }} will just render the string {{ contenido }}. That made me realise that safe` is not mentioned in the docs, I'll add it
